We're geting down to the nitty gritty now! Looking for a 3 or 4 bike, class 3, 2" hitch rack that either extends far enough away from the rear end or tilts/swings away to enable either partial or full (preferred) opening of the rear compartment. Nearly all of the tilt/swing models I've looked at specifically state they are not designed for RVs/trailers due to the greater distance on these from the rear axle to the back of the unit (increased bounce?). Currently using a buddy's platform 2 bike mount & squeezing into the rear compartment for the power plug/hose/gloves whenever we stop.
